Description: In this thesis, autogenous deformation of cement pastes, Normal Weight Concrete, and Lightweight Aggregate Concrete are measured. Both Portland and Blast Furnace Slag cement are studied. A model for calculating self-desiccation shrinkage of cement paste is proposed and validated with experiments. Shrinkage of NWC is derived with a composite model and early-age expansion of LWAC, a puzzling phenomenon up to now, is explained. Finally, transport of water from saturated lightweight aggregates (LWA) to hardening cement paste is measured with x-ray absorption.
